But at present the forests that can be cut down are fewer, so that the forestry industries are very difficult, and the situation has been very hard for the economic activities for the people there and the sustainable development of the city. Under such background, this paper does research on the problem of the sustainable development in the forestry resource-based city, find the relationship between the cut of the forest and economic development, and the problems in the economic develop process and the reasons of the declining. Then I construct the dynamic model of the sustainable development in economic in Yichun, in order to find the reciprocities among the population, resource and economics to provide more scientific data to the deciders. From the model, we can get the sustainable mode in the forestry resource-based cities.

本文就是在这种背景下，研究林业资源型城市的经济可持续发展问题，探讨林业资源开发与经济可持续发展的耦合关系，以及林业资源型城市经济发展存在的问题及经济衰退原因，并通过建立伊春市发展的系统动力学模型，进而揭示出城市发展过程中，人口、资源、经济之间的相互作用关系，为决策者做出正确的决策提供更加科学准确的技术支持，试图找出林业资源型城市可持续发展的系统优化模式，同时，把系统动力学方法引入林业资源型城市经济可持续发展研究领域，为解决相关问题探索一种新的方法与思路。

The dynamic model and equivalent circuit are researched, A dynamic model and equivalent circuit in d-q frame of dual three-phase synchronous machine are presented for the first time, based on the analyzing of the inductance factor between the windings of synchronous machine under ideal conditions. From them, a dynamic model and equivalent circuit that has general significance is educed.

基于理想同步电动机模型，以相绕组为研究对象，对双电枢绕组同步电动机的动态数学模型进行了研究，首次推导出双电枢绕组同步电动机在d-q坐标系的动态数学模型，绘出了d-q坐标系等效电路。

Through research and analysis of data, it was observed that the length and width of bark fiber varied according to the lop and age, the results show the fiber of the Salix bark is longer than the Salix and width of fiber almost same, fiber length of the Salix bark mainly influenced by the times of lop. The ash in Salix bark,1% Sodium Hydroxide Solubility in Salix bark, water solubility in Salix bark, Ethanol-Toluene in Salix bark, acid-insoluble lignin in Salix bark changed with the lop and age is also been investigated, the component of Salix bark is higher than Salix except acid-insoluble lignin,and it's high effected by times of lop; the TG analysis and DSC analysis is been used on the Salix bark and Salix to study the character of the hot-action, and the rang of the pyrogenate temperature is confirm; the quantity of Salix bark effect on the MOR, MOE, swelling in 24h water, nail withdraw and inner strength was determined, the results show that the Salix bark notability effect on the properties of board and dropped it; the properties of the Salix bark board is nearly the board product by other bark residues, it was established the multi regression equation of each properties and optimized the fitting produce condition of Salix bark board.

通过试验和数据处理，得出了沙柳树皮纤维长度、宽度随平茬和材龄的变化规律，结果表明沙柳树皮长度要比沙柳材的要长，宽度基本相同，沙柳树皮纤维长度主要受平茬次数的影响；找出了沙柳树皮中灰分、冷热水抽出物为、1%NaOH抽出物为，甲苯乙醇抽出物、酸不溶木素与平茬次数和材龄之间的关系，除酸不溶木素外，其他成分均明显高于沙柳材，沙柳树皮的化学成分主要受平茬次数的影响；利用TG和DSC法分析了沙柳树皮和沙柳材的反应热特征，确定了热解的温度范围；研究了沙柳树皮量对于刨花板MOR、MOE、吸水厚度膨胀率、握钉力以及内结合强度的影响，结果证明沙柳树皮量对于刨花板的各项性能指标影响显著，它的掺入降低了刨花板的各项性能；对沙柳树皮板的研究表明，沙柳树皮板的各项性能与同类树皮板的性能基本相近，建立的二次回归模型稳定，并利用回归方程求出了适宜的沙柳树皮板制造工艺。

After the cut-off frequency has been determined, the active noise-filtered system can be designed with several circuits to filter out those frequencies higher than the cut-off frequency and reserve the speech voice only. Besides, the music signals from the MP3 or a CD player can also be transmitted to the earplug system for increasing the signal noise ratio. The anxiety and tension of patients during treatments can, thus, be relaxed due to the euphonious music and toothaches of the patient might be further reduced.

本研究首先以离线的方式收集各类牙科噪音，然后将它传递到个人电脑，并使用CoolEdit及LabVIEW软体程式，分析出在牙科治疗过程中所产生之噪音的频率范围，最后透过各种比较，找出适当的截止频率，在截止频率(1KHz)被决定之后；针对该截止频率，使用主动式滤波的方式设计出相关的电路，组成主动式噪音率除系统，来滤除那些高於截止频率的噪音信号，只保留语音频率范围；此外透过mp3或cd player所播放出的音乐讯号，也可以同时被传递到耳塞系统来增加信号杂讯比，那麼当病人在治疗时，因为有这音乐可以使病人的焦虑跟紧张获得舒缓。
